Programming
As supplied, the module is programmed for 4-aspect signals. If you are using 3- or
2-aspect signals, then it will be necessary to reprogram the module.
Programming for the particular application can be completed before or after testing
the wiring, and also before or after completing the installation.
This is performed by attaching the sensor inserting a link between the A and K
terminals and
holding down the Push Button when switching on the power
(it
will also work if the Infra-Red sensor has been connected to the A and K terminals).
For each program there are two values to be stored (see late for details of the
options available).
The red led on the PCB flashes at 1 second intervals. When the required number of
flashes is seen (see later for the list of possible choices) the button is released to
store the first value. At this point the led comes on for five seconds to confirm the
value is stored.
The led then starts flashing again, and this time the button needs to be pressed to
store the second value.
Once both values have been are entered, the led flashes 10 times rapidly, and the
module starts operating.
Each value entered can be up to 255 flashes. If more are seen, or the programming
is aborted by switching off, then the programming must be repeated.
